Technical specs

General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

Video outputs and ports

Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones (so-called Founders Edition for NVIDIA chips). OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.

3DMark Cloud Gate GPU

Cloud Gate is an outdated DirectX 11 feature level 10 benchmark that was used for home PCs and basic notebooks. It displays a few scenes of some weird space teleportation device launching spaceships into unknown, using fixed resolution of 1280x720. Just like Ice Storm benchmark, it has been discontinued in January 2020 and replaced by 3DMark Night Raid.

3DMark Fire Strike Score

GTX 980 SLI Mobile 18339
RTX 3080 Laptop GPU 21480 +17.1%

3DMark Fire Strike Graphics

Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.

RTX 3080 Laptop GPU 27000 +6.1%

3DMark 11 Performance GPU

3DMark 11 is an obsolete DirectX 11 benchmark by Futuremark. It used four tests based on two scenes, one being few submarines exploring the submerged wreck of a sunken ship, the other is an abandoned temple deep in the jungle. All the tests are heavy with volumetric lighting and tessellation, and despite being done in 1280x720 resolution, are relatively taxing. Discontinued in January 2020, 3DMark 11 is now superseded by Time Spy.

Advantages of NVIDIA GeForce GTX 980 SLI Mobile

3.4% better performance in benchmarks

CUDA (Compute Unified Device Architecture - an API for video card computing power usage in tasks different from 3D graphics processing. Can be used for physics simulation for instance)

PhysX (hardware acceleration of physical simulation engine named PhysX)

G-SYNC (removes screen tearing by telling the display when to renew the image. Only works with G-SYNC compatible displays)

Advantages of NVIDIA GeForce RTX 3080 Laptop GPU

Much newer (12 January 2021 vs 22 September 2015)

More pipelines (6144 vs 4096)

Finer manufacturing process technology (8 vs 28 nm)

So, which one is the better GPU?

Technical City couldn't decide between NVIDIA GeForce GTX 980 SLI Mobile and NVIDIA GeForce RTX 3080 Laptop GPU. The differences in performance seem too small.
